Shapes & the Right Angle
Instructional Objective (Measurable)
After the lesson student should be able to:
1. Recognise different shapes and their properties.
2. Recognize whole, half and quarter turns; identify that angle that measures a
quarter turn called a right angle.
identify right angles in the environment and contained in 2-D shapes.
Qatar curriculum Standard:
7.1 know that angle measures the amount of turn and recognise whole, half and
quarter turns; know that angle that measures a quarter turn is called a right
angle.
7.2 identify right angles in the environment and contained in 2-D shapes.
Materials:
1. Different color of shapes (red circle, green triangle, orange square and
yellow rectangle).
2. The white board and the markers.
3. 4 pieces of worksheet 1.
4. 26 pieces of worksheet 2.
5. 26 piece of worksheet3.
6. PowerPoint slides show 1(The shapes).
7. PowerPoint slides show 2(The right angle).
8. PowerPoint slides 3(Who am I).
9. Flash cards of the words side, corner and angle.

TEACHING PROCEDURE:
1
Activating prior Knowledge/ Focus:
1. Show the students on the board different color of shapes (red circle, green
triangle, orange square and yellow rectangle), then ask them “what we
call these objects?” When they answered ask them “can we make face
with these shapes?”
2. Draw a circle and have them choose which shape to be the eyes, mouth
and Nose and that is by saying the shapes name then to go to the board
and to fix the shape in the correct place of the face.
3. Point to the rectangle and the square then ask them to compare between
these two shapes (the rectangle and the square).When they said their
knowledge by answering your question then tell them today we are going
to learn the properties of shapes. And to recognize the right angle.
Teacher Strategies
Students Activities
1. Share with students the discussion The students will tell their knowledge
about each shape’s properties (square, about the properties of the shapes
rectangle, triangle and square).
(square, rectangle, triangle and
square).
2.Attach flash cards of the words side,
corner and angle on the board and ask
the students to work in group and to
think about the square:
 How many side it has?
 What we call its sides?
 How many corner it has?
 What we call its corners?
The students will work in group to
Do the same for each shape of oblong, find the teacher’s questions answers
circle and triangle.
about the different shapes.
3. Show them Shapes (PowerPoint) and
let them spot the corners, the sides and The students will spot out the corners,
the right angles.
the sides and the right angles.
4. Give them worksheet 1 to work in The students will work in group to
group and to solve it.
solve the worksheet 1.
5. draw a square on the board and
point to the corner then ask”What does
each corner make?”
“Angle”
6. Ask” How many angle square,
2
oblong, and circle have?”
Draw each of the above shapes on the Students will count the angles and
board and let them count and point out will point out that “square has 4,
the angles.
oblong has 4 and circle has 1”
7.Show them the quarter, half and the
whole of the angle and how much
degree each of them is, by drawing a
circle on the board and explaining how
the angle moves and increases to reach
to 90 which is a quarter of the circle
area then it moves and increases to
reach to 180. Show them on the circle
area that it is half of the circle area
then explain that it will turn around to
reach to 270 which is 3 fourth or 3
quarter of the circle and then it will
make complete turn which is 360 to
make complete circle and it called a
whole.
8. Let them figure out the right angle The students will figure out the right
in different shapes through the angle in different shapes through the
PowerPoint slide’s show.
PowerPoint slide’s show.
9. Distribute worksheet2; explain for
them the questions and what they
have to do, and then ask them
individual to figure out the right
angles in the given shapes make. Move Individual the students will figure out
in the class around them to check their the right angles in the shapes given in
work and to scaffold if it is needed.
worksheet2.
Modifications/ Differentiation:
* Peer-tutoring and teacher-led small group instruction will help the students
with difficulty understanding to understand shapes properties and the right
angle.
* Answering worksheet (1). This worksheet helps the students to learn and to
point out different shapes properties, while worksheet (2) helps them to figure
out right angles.
* PowerPoint’s slides shows help the students with difficulty understanding to
visualize the shapes properties and the right angle.

Lesson Extension:
Play with the students guessing game (Who am I?) through the PowerPoint
slides show, which helps them to point out the shape name depending on its
properties and identification.
Closure:
Ask them “what did we learn today?” Have them count and tell what they
learned about shapes properties and let them identify the right angle. Tell them
tomorrow we will learn about the 3d shapes.
Assessment:
1. The teacher will assess the students through their participation in the
lessons activities and answering the teacher’s question.
2. The teacher will assess the students through their answers of questions in
the worksheets 1 & 2.
4. Teacher will give the students home work ( worksheet 3) to assess them
by answering the questions:
 Describe what a right angle is?
 Find 9 objects that have right angle in them. Draw them?
